Description

The The invention relates to a method for producing a prefabricated reinforced with steel bars, in particular a ceiling or wall element, with at least one pipe for room temperature control. In addition, the invention relates to a retaining rail for use is formed in a method of this type.

Especially In commercial buildings, but also in housing, it is more and more common blankets and walls with piping for room temperature control, whether for heating or Cooling, to use. Due to time and cost reasons today are on construction sites very often used prefabricated or semi-finished parts.

Should a semi-finished part are provided with piping through which afterwards the cooling or heating fluid flow should, on the one hand, it is possible to manually insert these pipes in the concrete plant on site. To However, a lot of time is needed and it still exists the problem that the manual insertion of the pipes only difficult in the partially fully automatic production process in the concrete plant integrate. moreover let yourself insufficiently secure the laying distance of the pipelines.

From the DE 198 48 561 A1 a method is known in which a pipe register is integrated with a static supporting reinforcement mat in a reinforced concrete semi-finished part. However, this method is based on the use of reinforcing mats, which are associated with a higher production and cost compared to steel bars. In addition, the logistical effort is much higher than with the use of steel bars, for example in planning, mat production, during transport to the production site and during installation. In addition, there is again the problem of the difficult integration of the method in a fully automatic production in concrete plants. Therefore, it is for economic reasons advantageous to use in the production of ceiling and wall elements bar reinforcements.

Of the Invention is therefore based on the object, a process for the preparation a prefabricated reinforced with steel beam component of the beginning specify the type mentioned, the improved installation of pipelines on site in concrete plants.

• – Einbringen wenigstens einer Halteschiene für die wenigstens eine Rohrleitung und Halterung der Halteschiene an der Bewehrung,
• – Einbringen und Halterung der wenigstens einen Rohrleitung an der Halteschiene, und
• – Verguss des Bauelements mit Beton.

To achieve this object, a method for producing a prefabricated reinforced with steel bar component, in particular a ceiling or wall element, provided with at least one conduit for room temperature control, which comprises the following steps:

• - creation of the bar steel reinforcement,
• Inserting at least one retaining rail for the at least one pipeline and securing the retaining rail to the reinforcement,
• - introducing and holding the at least one pipe to the support rail, and
• - Potting the component with concrete.

at this procedure is first the statically necessary reinforcement for a ceiling or wall element od. Like. By means of steel bars manually or fully automatically in the production range created. Thereafter, a holding or fastening rail is introduced and at the statically necessary reinforcement, whereby in the Usually several such rails in a distributed arrangement depending on the laying pattern the pipelines are introduced. The rail is used for recording the for the room temperature required piping, after their introduction and finally mount the potting of the device can be done with concrete. Subsequently, will the prefabricated component from the concrete plant to the construction site transported, where the installation of the ceiling or wall elements takes place. On the construction site, the upper reinforcement is applied, after which the entire element is shed with concrete.

It is advantageous if the pipeline cliphaltert to the retaining rail becomes. By clipping the pipe is fast on the one hand and securely held, on the other hand can thus a defined installation distance guaranteed become. Conveniently, lies in the introduced into the device to be manufactured pipeline higher than the bar steel reinforcement. Thus, the basic structure remains, for example an element ceiling unchanged, while one approximately uniform temperature control can be ensured in different directions.

The Bar steel reinforcement is usually with a longitudinal and a transverse reinforcement created. After a first training of the inventive method is provided that lattice girder can be used, which are introduced before the retaining rail in the device become. This is usually a fully automated manufacturing process in the concrete plant the case. Then the transverse and longitudinal reinforcement as well as the lattice girders introduced in one step directly after each other.

Alternatively, it is also possible that lattice girders are used which are introduced into the component after the retaining rail. This possible It consists of semi-automatic or manual production.

In order to offers the method according to the invention the advantage that the device with the Raumtemperierungsfunktion on the one hand manufactured without problems in a fully automatic concrete plant can be, but on the other hand variations are given, the in a semi-automatic or manual production advantageous could be.

Farther can be provided that the retaining rail to the longitudinal reinforcement and / or is supported on the lower chords of the lattice girders. So that can slippage of these components against each other are prevented and the entire component receives additional Stability. In a fully automated manufacturing process where the bar steel reinforcement and the lattice girders Inserted directly one after the other, a holder is at least on the lower chords of the lattice girders, possibly also on the longitudinal reinforcement, easily possible. Become the lattice girders only after the retaining rail introduced, for example, in a manual Manufacturing process, so a holder is recommended only on the longitudinal reinforcement.

The Retaining rail in the method according to the invention can force fit held on the reinforcement and / or on the lower chords of the lattice girders become. Particularly advantageous is a clip holder of the retaining rail at the reinforcement and / or the lower chords of the lattice girders, so defined distances between rail, reinforcement and lattice girders can be secured.

A Embodiment of the method according to the invention provides that the pipeline or piping to the bar steel reinforcement be attached.

This can, for example, force fit respectively. For example, you can Cable ties or wires used become. The pipelines are usually in turns like this misplaced that in the area of the component run parallel, while in the edge region, the deflection he follows. In particular, to secure the pipeline against floating in the deflection area a fixation to the reinforcement required. By further fixations in the parallel sections may additionally Slipping can be prevented.

According to the invention can be provided be that the retaining rail transversely, in particular perpendicular, to the longitudinal reinforcement is introduced. This is useful because the longitudinal reinforcement usually on the transverse reinforcement rests, so that in the subsequent introduction the support rail orientation to the longitudinal reinforcement and the bracket at the longitudinal reinforcement is beneficial.

In addition, the invention relates to an alternative method for producing a prefabricated reinforced with steel beam component, in particular a ceiling or wall element, with at least one conduit for room temperature, with the following steps:

• Inserting at least one retaining rail for the at least one pipeline with a bearing surface for the bar steel reinforcement by placing it on a formwork of the component,
• - creation of the bar steel reinforcement,
• - Introducing and holding the at least one pipe to the support rail and
• - Potting the component with concrete.

in the Difference to the previously described method is in this method first put the retaining rail on the formwork. Only then done creating the necessary reinforcement. The pipeline will turn in turn held on the support rail and finally the component with concrete shed. In this method, the retaining rail additionally as Spacers serve the lower reinforcement. Because of the static Reinforcement on the rail rests, a dislocation of the Rail prevented.

A First embodiment of this method provides that lattice girder used be introduced in front of the pipeline. This would be the same Procedure for a fully automatic production process in which Transverse, longitudinal reinforcement and girder be introduced directly in succession in one step.

alternative it is again possible that lattice girder used, which are introduced after the pipeline, for example in a semi-automatic or manual process.

advantageously, the pipeline is clamped to the retaining rail clip. That's one rapid pipe laying guaranteed with a safe installation distance.

Depending on the design of the retaining rail, the pipe may be higher when the retaining rail inserted as the bar steel reinforcement; In addition, an attachment of the pipe to the bar steel reinforcement, which takes place for example non-positively, be advantageous. In the deflection region, such fixing of the pipes to the static reinforcement is generally required, for example fixing by cable ties in order to prevent slippage. In contrast, with a correspondingly selected installation spacing of the retaining rails, a fixing of the pipeline in the longitudinal direction, ie in the sections lying in parallel, is only punk completely or not necessary.

In summary enable both alternative methods according to the invention an economical production of a prefabricated component with piping for room temperature control, at the same time a secured laying distance of the pipelines is guaranteed.

Besides The invention relates to a retaining rail, designed for use in the first of the two methods characterized that they have on their underside devices for mounting on the Reinforcement, in particular clip devices, and on its top Devices for holding the pipeline, in particular clip devices, having.

The Names top / bottom refer to the in the production pallet introduced holding rail.

Here the device holders are on opposite sides the rail, which makes the pipeline higher in the finished device comes as the static reinforcement.

The Retaining rail can as well on its underside devices for holding the lattice girders, in particular Clip devices have. This is an advantage in the case where the transverse, longitudinal reinforcement and the lattice girders be introduced directly in succession and in front of the retaining rail. Then the rail can not only on the longitudinal reinforcement, but in addition also at the trusses be clipped, making all components to each other a solid Location received.

Become the lattice girders introduced after the retaining rail, so the retaining rail makes sense on its upper side a support surface for lattice girders. This bearing surface can opposite the other rail surface be lowered so that they are at the level of transverse reinforcement or directly above the Transverse reinforcement is located. Preferably, the lower chords of the lattice girders are in the Plane of longitudinal reinforcement. This can be the subsequent Insertion of the lattice girders be made easily.

In order to the tool costs for the production of the retaining rail in one move economic frame, it makes sense to support rails with a length of about 1 meter to use. This has the additional advantage that in the case in which the lattice girders be introduced in front of the retaining rail, a slight threading the Retaining rail in the lattice girders possible becomes.

Besides The invention relates to a retaining rail for use in formed the second method and characterized in that they have on their top devices for holding the pipeline, in particular clip devices, and a support surface for the reinforcement having.

These Rail is thus suitable for placement on the formwork, in which first the bar steel reinforcement is placed before the pipeline into the Clip devices, also on the top of the rail, supported becomes. These clip devices expediently protrude beyond the surface of the rail, so that the pipeline higher lies as the reinforcement.

The Retaining rail can be a profile, in particular a U-profile or H-profile or L-profile, with recesses in the longitudinal direction. These recesses can arbitrarily, z. B. semicircular, oval or circular be educated. It is important to ensure that the installation the rail is not affected by the recesses. The rail should not with sufficient stability include too much material.

In This sense is a filigree in all inventive retaining rails Construction of advantage. The support rail should be fine and with little material be formed so that they are potting the element with concrete not disturbing works and the even distribution of the concrete is not affected. Such education leaves Realize yourself particularly well with plastic rails.

The Support rails according to the invention enable it, even when using the more economical bar steel piping for room temperature control quickly and with a secured installation distance relocate. This is both concrete plants with a fully automatic Manufacturing process, as well as in the case of a semi-automatic or even manual production process possible.

Further Advantages, features and details of the invention will become apparent the embodiments illustrated below and with reference to the Drawings. Showing:

1 a device produced by a method according to the invention with introduced after the reinforcement rail before potting with concrete;

2 in the process after 1 used retaining rail;

3 a manufactured according to another inventive method component before the casting with concrete;

4 in the process after 3 used retaining rail;

5 a manufactured by a process according to the invention with erected on the formwork rail component before the casting with concrete; and

6 in the process after 5 used retaining rail.

1 represents a device produced by a method according to the invention 1 in which the retaining rail 7 was introduced after the reinforcement. The component 1 has not been shed with concrete yet. It includes a formwork 2 , on the spacers 3 for the transverse reinforcement 4 have been applied. Perpendicular to the transverse reinforcement 4 is the longitudinal reinforcement 5 This statically necessary reinforcement was produced by means of steel bars manually or fully automatically in the production range. The subsequent introduction of the lattice girders 6 is done so that their arrangement is adapted to the planned pipe installation. The retaining rail 7 has on its top and bottom clip devices 8a . 8b on, on the bottom for clipping the longitudinal reinforcement 5 serve while on the top the piping 9 be clipped. In addition, the clip devices serve 8b for clipping the lower straps 10 the lattice girder 6 , The retaining rails 7 , of which in the present device 1 two are shown, are filigree, so that the casting with concrete is not hindered by the support rails. The length of the support rails 7 may vary, with a length of about 1 meter being appropriate to both a convenient manufacture of the support rails 7 as well as easy threading into the lattice girders 6 to allow during assembly. The spacing of the individual retaining rails 7 is chosen here so that the parallel sections of the piping 9 approximately equidistant.

After casting with concrete, the finished component can be transported to the construction site and mounted there. As with this device, the transverse reinforcement 4 , the longitudinal reinforcement 5 and the lattice girders 6 can be introduced directly consecutively, a production can be carried out in a fully automatic concrete plant, at the same time a secured installation distance of the pipeline 9 given is.

In 2 is the in the process after 1 used retaining rail 7 shown. You can see the clip devices 8a on the top of the retaining rail 7 responsible for receiving the pipelines 9 are meant. The clip devices 8b on the underside of the retaining rail 7 serve for clipping the longitudinal reinforcement 5 and the lattice girder 6 , The plastic retaining rail 7 is filigree, so that its structure does not hinder the encapsulation of the component with concrete.

3 shows a manufactured according to another inventive method device 11 before casting with concrete.

The component 11 again has a formwork 12 as well as spacers 13 for the transverse reinforcement 14 on. The longitudinal reinforcement 15 lies perpendicular to the transverse reinforcement 14 on.

The retaining rails used here 16 turn on their top clip devices 17a on, to pick up the pipes 18 serve. Into the clip devices 17b on the underside of the retaining rails 16 are the corresponding sections of the longitudinal reinforcement 15 clipped. The retaining rails 16 have contact surfaces 19 , which are lower than the other rail surface. On the bearing surfaces 19 become the lower chords 20 the one after the retaining rails 16 introduced lattice girder 21 established. Not shown here is in particular in the deflection of the pipes 18 required fixation of the pipes 18 at the static reinforcement. By the laying distance of the support rails 16 is such a fixing in the longitudinal direction, ie the parallel sections of the pipes 18 only occasionally or not necessary.

The insertion of the retaining rails 16 before introducing the lattice girders 21 is particularly suitable for manual or semiautomatic production processes in the concrete plant. Only at the construction site, the introduction of an upper reinforcement and then the casting with concrete.

4 shows the in the process after 3 used retaining rail 16 , The clip devices 17a on the top of the retaining rail 16 responsible for receiving the pipelines 18 serve, have greater distances than the clip devices 17b on the underside of the retaining rail 16 , Through the numerous clip devices 17b on the bottom of the rail 16 , in which the longitudinal reinforcement 15 can not be clipped, it is not necessary when creating the reinforcement, the subsequent introduction of the retaining rail 16 or the pipes 18 to take into account. Only for the introduction of the lattice girders 21 on the bearing surfaces 19 results from the position of the bearing surfaces 19 a restriction. The lattice girders 21 are adapted to the planned pipe installation on the bearing surfaces 19 then put up the pipes in the clip devices 17a on the top of the retaining rail 16 be clipped.

5 represents a device produced by a method according to the invention with erected on the formwork rail component 22 before casting with concrete. The on the formwork 23 mounted holding rail 24 has recesses in its longitudinal direction 25 on, so that the subsequent casting with concrete is not hindered.

On its top are bearing surfaces 26 to see on which the transverse reinforcement 27 is hung up. On the transverse reinforcement 27 again lies the longitudinal reinforcement 28 on, next lattice girder 29 with her lower straps 30 , The lattice girders 29 can be before or after the piping 31 depending on whether the manufacturing process fully, semi-automatically or manually. The pipelines 31 be in the clip devices 32 the retaining rail 24 clipped. The piping can be realized quickly and economically.

Thus, in the method in which the retaining rail 24 directly on the formwork 23 is set up, yet a smooth surface of the device is created, make sure that the recesses 25 are formed such that the retaining rail 24 with sections tapering towards the surface on the formwork 23 gets up. A dislocation of the rail is in this embodiment by the weight of the static reinforcement, on the rail 24 rests, prevents.

6 Finally, the in the process after 5 used retaining rail 24 dar. The retaining rail 24 has a U-shaped profile, wherein in the longitudinal direction numerous recesses 25 available. These recesses 25 can be round or oval or take any other appropriate form. On the top of the retaining rail 24 are the clip devices 32 for receiving the pipes 31 , These clip devices 32 can be adapted to the desired pipe installation in recesses 25 the retaining rail 24 be held. By the subsequent holding the clip devices 32 is it possible to use the retaining rail 24 to be used for different pipe laying distances. The numerous recesses 25 allow easy casting of the device 22 with concrete and also serve to prevent the surface texture of the finished component 22 is impaired.

With this retaining rail 24 becomes the component 22 of the 5 produced, transported to the site and mounted there. Subsequently, the application of an upper reinforcement and the potting of the entire component 22 done with concrete. Alternatively, the component may be used without upper reinforcement and not concreted,
